在B800光谱的单个LH 2复合物从Rhododocellum molischianum的BChl a的反射显示突然的,可逆的光谱跳跃之间的有限数量的光谱位置。从我们的数据中,我们得出结论,这些波动的结果从构象变化的蛋白质骨架附近的发色团,这提供了一个敏感的工具来监测本地调制的色素-蛋白质相互作用。
The BChl a absorptions in the B800 spectrum of individual LH2 complexes from Rhodospirillum molischianum show sudden, reversible spectral jumps between a finite number of spectral positions. From our data, we conclude that these fluctuations result from conformational changes of the protein backbone in close vicinity of the chromophores which provides a sensitive tool to monitor local modulations of the pigment-protein interaction.
